Specifically, the water outlet of efficient flocculating clarifying reaction device is directly injected into fiber contacts precipitation filtration apparatus, trickle in water
Flco is combined with intercepting fiber collision, is adhered on fiber, and trickle flco extremely adsorbs on existing flocks body again afterwards, is formed
Floc sedimentation.Floc sedimentation increases to a certain extent, due to gravity and Automatic-falling settles, intercept fiber can recombine again it is new trickle
Flco.So in cycles, constantly update, water quality is purified.Its maximum feature is that interception fiber is not fixed viscous with flco
Connect so that process can be carried out continuously, and fiber withstanding caustic is stronger, and the service life is up to the several years.Wherein, fiber is intercepted through chemistry
The protophyte fiber binding of processing is built up multilayer lattice-shaped with certain arrangement mode and is intercepted into specific column brush-like structure
Body, is generally handled intercepting fiber using low-concentration sodium hydroxide or " low-concentration sodium hydroxide+sodium hypochlorite ", mainly
Remove the impurity such as the organic matter in protophyte fiber.The layout density for intercepting fiber has important shadow to intercepting precipitation turbidity removal efficiency
Ring, can be definite by calculating and optimizing, intercepting the specific laying form of fiber composition Engagement Area should set according to former structures are actual
It is definite to integrate to count structure.
More specifically, as shown in figure 4, the length direction for intercepting fiber is vertical with direction of liquid flow, trickle flco is adsorbed in
Fiber surface and mutually aggregation flocculation are intercepted, is known as adsorption flocculation.Trickle floc particle with certain flow rate and settling velocity
Due to intercepting fiber inhibition, two kinds of changes may occur for its movement locus:1. intercepted body retention, forms contact and inhales
It is attached；2. the strong turbulent fluctuation effect produced due to intercepting fiber to current makes particle depart from original current streamline, the direction of motion and speed
Degree changes, and the fine floc particle in adjacent fluid layer produces velocity gradient and easily combines cohesion.Trickle flco is blocking in water
Cut making contact in fiber surface and ambient water and adsorption-flocculation is deposited on interception fiber surface, be combined into larger floc sedimentation.
Flco network layer is formed on active cross-section, more effectively Contact-sorption occurs with follow-up micro-floccule.Intercepting fibration
Under, the size of flocculate and density not only formed is larger, but also the size distribution of flco due to occur restructuring more they tend to uniformly, because
This, sinking speed is fast, and delivery turbidity is low.
When intercepting fiber use at initial stage, what its retention absorption to floccule body was mainly realized by three kinds of modes:One
It is gravitational settling；Second, the vortex that particle periphery water body scale does not wait cause floc particle in the random motion of three dimensions and
Cause and adsorbed with the collision for intercepting fiber；Third, direct collision of the floc particle with intercepting fiber forms Contact-sorption.With blocking
The progress for the process of cutting, Engagement Area floc particle concentration incrementally increase, and Engagement Area gradually forms contact condensation region.In contact condensation region
Endoparticle flow velocity will be late by the horizontal flow velocity of sedimentation basin, this hysteresis effect for micro-floccule occur again flocculation create it is good
Good water project situation, while beneficial to the performance for intercepting fiber collision precipitation, contact cohesion.
Floc particle is carried out with intercepting the collision precipitation process of fiber in sedimentation basin Engagement Area three dimensions.It is this
Effect has the characteristics that polytropism and short distance, intercepts the hydraulic characteristic(s) and the mechanism of action of fiber uniqueness in addition, so intercepting fiber
There are good retention functions to the tiny flocculation body particle of settling property difference, this is to intercept sedimentation basin than traditional sedimentation basin with high
The main reason for imitating turbidity removal effect.Intercepting fiber interception hydraulic load, (unit intercepts body length and is handled within the unit interval to rule
